a Worm pinion 1A, which is secured on it. `is

driven all the mechanism that rotates the aXle 2, that rotates the gro-und treading tracks or the ground rolling Wheels of tractors, Whichever may be operatively connected to the opposite ends of the axle 2, Which are either directly or indirectly' driven by the said axle 2.

This motor driven shaft l, is housed in one end of an elongated casting 3, that pro! jects above the platform portion 4, of a tractor. The casing 3, is provided With a depending iiange portion 3A, which is bolted to the platform 4, by bolts 3B. A reinforcement plate 3C, is placed between the flange of the casing 3, and the platform 4.

The platform 4, has a thin steel vvearplate 5, that is secured to its under side, and a Wear plate 6, is held upagainst'the Wear plate 5, by a thick plater', that forms the connecting plate between the underside of platform 4, and the pivotal huh portion `8, of the casing 3, with the trucks of the vtractor and their endless grou-nd treading' trac/lul.

These trucksand their tracks are not illustrated, of Which there'are either one or'tivo under all tractors that use ground treading tracks .as their mechanism for moving' over the ground; lout the present' oiling mechanism forthe motor driven parts yot' tractors has .K been especially designed for endless ground treading track typesof tractors, and oonsequentl7 there have been illustrated in the'sectional view, Figure 1,'sprocket Wheels 2^ and 2B, secured on the opposite eues of the axle; and the links 2C, of an endless track are shown in section, in engagement'with the teeth of the sprocket Wheels. Full side vicivs of` the trucks to which the plate 7,1isattached, and a full side view of the endless ground treading tracks are fully illustrated and described in the pending application, Serial Number 374,743, .tiled April 17, 1920.

The present oiling mechanism is positioned on the tractors between the said motordriven shaft l, and the axle 2, and applies to them and their intermediate connecting mechanism.

The hub 8, is preferably an integral part portion extends loosely through, but fits closely in an aperture 9, formedthrough the v that'are threaded to the axle.

truck supporting plate 7, and its wear plate 6, which rest on top of the upper end of a hub 10, that forms a part of a "l" or .crossplatel, that fits snugly around the shaft,y

and its outer edge is secured in an: annular recess 16, that is formed in the inside ofthe outer terminal/'ends of the endsvofy the casting 11,;by a ring 17.

These end plates keep dust and dirt from. entering the ball bearings atthe opposite ends of the casting that surrounds` the shaft,

vand at the same time they prevent the oil which'works downwardly'from the casing3, from running freely out of this casting through the ball bearings;y as the oil works into and through them to these end plates 15, and collects on top ofay central casting 18, that forms the bottom portion 'of the T-shaped casting 11, that surrounds and-supports the axle 2'. This casting'18, is. removably secured to shouldered end port-ions 19,

that are formed on the bottomfof the east-r ing 11, around the edges ofan opening 20, formed in the bottom of the casting 11, and` this removable bottom portion' 19, of the casting is provided, in order to remove the oily sediment that collects there, as well as to examine the ball bearings and `the ,other parts of the shaft, both at the; time of assembling them .together and also from time to time when the-tractor isfin; use.

The-casting :3, is provided with a large opening in its top portion which is closed by a cover 21, that isy removably secured to the casing 3, cap screws 22, and thiscover is provided with an aperture 23, that is screws 25B.

ball bearing 32, the opposing half part j v Betweenthis ball bearing and the bevel" gear, any open topped oil cup between thin washer shaped shims 34; the upper shims are used to adjust the mating parts ofA the ball bearing and the lower ones are used to'adjust the distance the teethof its bevel pinion 30, shouldl extend into the teeth of the bevel gear 31, toy rotatively drive the bevel gear with the best meshing `contact of the teeth obtainable.

On the upper end of the `vertical shaft 28,. a worm gear supporting hub, 34, is secured, preferably by being keyedthereto by semicircular keys4 35, that are set onto the shaft", and the hub is pro-vided with slots that allow the hub to be pressed` down over thekeys onto the shaft.l f

The hub 34, is provided with a short radiallange 36, that is bolted by bolts 37, tolugs k33, that are formedv of the rim portion 3f),

of'a worm gear 40, which meshes with the worm pinionv 1A, of ythemotor driven shaft 1. The projecting flange portion 36', of the hub 34, is providedwith ya thin vertically extending annular flange 41, that forms anr open top oil cup 42, 'and it projects up around the ballV bearing flange edge 26, of the cover 21, of t-he casing3, which isformed to depend below the-top of the cover in order. that an oil well or pocket is-formed around the lower portion of the upper ball bearingof the 4vertical shaft` 28.

`The easing 3,'A at the point where itspivotal center hub portion 8proj'ects ,downf wardly from it, is also providedwith an up-` wardly and wertically projecting annular flange member 44, the inner surface of which` extends up above the center of the motory driven shaft 1, and its worm pinion 1A, and above the center ofthe worr n\ rim 39,l and the louteredge of the flange of the worm gear 36, depending down below the end of' the hub 44, close to the hub44, and the upper top end of the hub 44, extends up close to the portion 45, of the flange 36, and is-above the center of the worm gear and its pinion,

As this ring 19, with the 'truck support i Y y casing which is bolted to the platform, it has to be oiled. Preferably, however, in-

stead of connecting it to the oil Well 46, of

the casing' 3, Aoil is applied to it through a threaded aperture 5l, that is formedin the casing that is positioned to'enter the upper end of the recess 48, and close' 'he aperture with a threaded plug 52. Y "lhe operationv of the automatically operating oiling mechanism for the interior mot/or driven parts of'tractors, is as follows: The oil Wells and cups heroin described are filled partially full of oil, preferably a mixed liquid and semi-liquid or hard grease oil. when these parts rareassembled together when setting up a tractor. Thus, the lower portion ofthe' aXles supporting T-shaped casting ll, is filled With oil abo-ut up to the eenterof the axle,` and the cup 33. at the lower ball bearing and the one formed in the Worin gear are also filledv about half full of this mixture. lVhen the tractor is to be put to Work the plug' 25A, is' removed from thc'oil inlet hole in the cap 23, and'liquid'oil is introduced thro-ugh it into the'casing,

through apipe or a hose, and the semi-liquidoil or hard oil, ifit is used, is forcedthrough this hole by a grease gun, and the oil thus introduced flowsv don'fnthrough'the upper ball bearing oftheyerti'cal shaft 28, into the oil cup 42, formed on the Worm gear, and enough oil is introduced to cause it to overdoiv from it into .the oilv Well of the casing 3, which fills up to the top of its annularly vertical. flange, which 'partizjilly submerges theworm pinion and the Worm gear. and the oil then overflows into the hollow hub 8, of the casing and runs dovvn through theball bearing` at the loWe-r end of the vertical shaft 28, andA fills and overflows the cup 33, and flows into the T-shaped casting 1l, Where it works into and llubricates the teeth of the bevel gears and also the ball bearings at the opposite ends of this casting. Thus all of the ball bearings of the axle and the vertical shaft and the Worm gearingr in the casing 3, and the bevel gears in the T-shaped casting, rotate continuously in oil, and if these rotating parts of a tractor is; plate i", turns on the hub 8, of the are thus supplied with oil at the beginning of a seasons Work on a farm or ranch, they canbe used continuously throughout the season Without beingre-oiled.

j T he invention provides a simple, inexpensive and throughly practical oiling mechanism for the interior motor driven parts of tractors, Whiclnwhile providing superabundant and continuous lubrication to all parts, at the same time removes prac tically all chance for the intrusion of dirt, grit and otherfinjurous foreign substances tothe. Working parts, and While these. have been illustrated and described vthe preferred construction and arrangement of it, it is not to be limited to it, as changes may be mad-e` Without departing from the spirit of the invention.
